  • Lambda control and adaption
  • Catalyst heating, temperature maintenance
  • Thermal protection and O2 storage balancing.
  • Catalyst oxygen storage determination and catalyst oxygen purge.
  • Engine start and enrichment
  • Canister purge control diagnostic functions.
  • Stop/Start strategy
  • Combustion functions
  • Perform development and validation testing in vehicles on road and on chassis & engine dynamometers (if required)
  • Develop and manage calibration variants supporting multiple vehicle types and target markets
  • Participate in test drives for cold, hot, and high altitude development and validation
  • Analyze and summarize data. Concisely report results, conclusions, and recommendations
  • Support the engineering team through mentoring and experience sharing
  • Bachelor / Master's in Mechanical, Electrical, or Automotive Engineering
  • 5 years of relevant experience
  • Hands-on experience developing calibrations to meet emission requirements
  • Hands-on experience understanding and working with complex control functions
  • Hands-on experience with calibration development tools such as ETAS INCA and Vector CANalyzer/CANape, Matlab
  • Electrical motor experience and/or combustion experiences a big plus
  • In-depth knowledge of: basic combustion processes, emission formation, emission control, and after-treatment systems
  • In-depth knowledge of emission/combustion testing procedures and regulations
  • Ability to facilitate issue resolution in cases of conflicting requirements between emissions, driveability, diagnostics, and fuel consumption
  • Excellent system-level problem solving skills
  • Excellent data analysis and presentation skills
  • Well organized, highly motivated, and able to work in a multicultural environment
  • Willingness to train additional employees in the subject matter
  • Knowledge of MS Office programs, email clients, and databases
  • Willing to travel domestically and/or internationally as required
  • Valid driver's license

Preferred Qualifications:

  • Experience with direct injection gasoline engines and hybrid powertrains. Calibration experience in other areas such as e-motor, base engine/combustion, OBD and emissions optimization
  • Ability to facilitate issue resolution in cases of conflicting requirements between emissions, driveability, diagnostics, and fuel consumption
  • Experience with control function development is a plus
  • Experience with high ethanol content fuels is a plus
  • In-depth emission certification & regulatory experiences is plus
  • German language a plus
